Census
Terrius in the 2020 Census
The 2020 Census recorded 165 people with the first name Terrius, which placed it at #43,061 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Terrius is Black at 92.1%. The next largest groups are Hispanic (3.6%) and Asian/Pacific Islander (1.8%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Terrius described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Terrius at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Terrius
The given name Terrius has its origins in the Latin language, dating back to ancient Roman times. It is derived from the Latin word "terra," which means "earth" or "land." This suggests that the name may have been initially bestowed upon individuals with a strong connection to nature, agriculture, or the earth itself.
During the Roman era, the name Terrius was often used as a cognomen, a type of personal name or surname, within Roman families. It was particularly popular among the Roman aristocracy and landowners, reflecting their ownership and stewardship of vast tracts of land.
One of the earliest recorded instances of the name Terrius can be found in the writings of the Roman historian Livy, who mentioned a Terrius Rufus, a Roman senator and military officer who lived in the 1st century BC. Livy's account suggests that Terrius was a respected figure in Roman society.
In the Middle Ages, the name Terrius became less common, but it did appear in various historical records and documents. One notable bearer of the name was Terrius of Auxerre, a 7th-century Frankish monk and scholar who authored several religious writings and played a significant role in the spread of Christianity in Gaul (modern-day France).
During the Renaissance period, the name Terrius experienced a resurgence in popularity, particularly among intellectuals and artists who drew inspiration from classical Roman culture. One famous bearer of the name was Terrius Phalamides, an Italian painter and architect who lived in the 15th century and was renowned for his frescoes and architectural designs.
In more recent centuries, the name Terrius has remained relatively rare, but there have been a few notable individuals who carried it. Terrius Eliades was a Greek philosopher and writer who lived in the 18th century and made significant contributions to the field of ethics and moral philosophy.
Another notable bearer of the name was Terrius Maximilian, a German explorer and naturalist who lived in the 19th century. He is remembered for his expeditions to various remote regions of the world, where he documented and studied numerous plant and animal species.
While not an exhaustive list, these examples showcase the rich history and diverse bearers of the given name Terrius throughout various eras and cultures, all connected by the common thread of their name's Latin origin and its connection to the earth and land.

FAQ
Terrius: questions and answers
How many people in the U.S. are named Terrius?
Name Census puts the figure at roughly 165 living Americans. We arrive at this by taking every SSA birth registration for Terrius going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 2,077,299 US residents.
Is Terrius a common name?
We classify Terrius as "Very Rare". It ranks above 71.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 168 babies have been registered with this name.
When was Terrius most popular?
The single biggest year for Terrius was 2008, when 13 babies received the name. The fact that the average living Terrius is about 25 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Terrius in the 2020 Census?
The published 2020 Census first-name tables recorded 165 people with the name Terrius, or 0.05 per 100,000 residents. That placed it at #43,061 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Terrius in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Terrius?
In the 2020 Census sex table, Terrius leans strongly male. 156 people counted with this name were male (95.7%), compared with 7 female bearers (4.3%). The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Terrius?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Terrius is Black at 92.1%. The next largest groups are Hispanic (3.6%) and Asian/Pacific Islander (1.8%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Terrius most often in the Census?
Black is the largest reported group for people named Terrius in the 2020 Census, accounting for 92.1% (152 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Terrius in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Terrius a male name?
Yes, 100.0% of people registered as Terrius in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Terrius still being used today?
Yes. The SSA still recorded Terrius in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Terrius can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate.
